Title: Polyol ester lubricants, especially those compatible with mineral oils, for refrigerating compressors operating at high temperatures
Inventor: SCHNUR NICHOLAS E
IPC: F25B1/00
Filed: 1994-10-31
Granted: 1997-07-24
Abstract: A high quality lubricant for compressors operated during at least part of their compression cycle at temperatures above normal human comfort temperatures, such as most automotive air conditioners, especially those using chlorine free hydrofluorocarbon refrigerant working fluids, is provided by mixed esters of hindered polyols, most desirably pentaerythritol, with a mixture of carboxylic acids including at least some iso-pentanoic acid along with one or more of iso-nonanoic acid, iso-octanoic acid, and dibasic acids such as adipic. When the mixture includes about 7 % adipic and amounts of branched C8-9 and C5 monobasic acids in a ratio of at least 0.75:1.00, the esters formed have excellent solubility for paraffinic and naphthenic mineral oils and are therefore especially well suited for lubricating vehicle air conditioners formerly containing chlorine containing heat transfer fluids and mineral oil lubricants.

Title: Malted beverage powder and process
Inventor: GEROMINI OSVALDO
IPC: A23L7/20
Filed: 1998-11-30
Granted: 2001-10-25
Abstract: A process for producing a malted beverage powder which reduces drying requirements. Malted beverage ingredients, which have a total moisture content of less than about 9% by weight, are introduced into an extruder and are extrusion cooked at a temperature less than about 150 DEG C. During extrusion cooking, an inert gas is introduced into the extruder and homogeneously mixed into the malted beverage ingredients to produce a gassed molten mass. The gassed molten mass is extruded through one or more orifices to provide an expanded extrudate which is then chilled to stabilise the expanded structure of the expanded extrudate. The expanded extrudate is comminuted to powder.

Granted: 2005-01-01
Abstract: Método para la incorporación estable de la capacidad de oxidación de hidrógeno a bacterias Gram negativas. La actividad de fijación de nitrógeno atmosférico por la nitrogenasa origina el desprendimiento de hidrógeno, disminuyendo el rendimiento energético del proceso. La presencia de actividad hidrogenasa, descrita en algunas cepas de Rhizobium, mejora dicha eficiencia energética. En esta patente se describe un método para transferir un sistema de reciclado de hidrógeno a distintas especies de Rhizobium y otras bacterias Gram negativas. El método se basa en el empleo de un minitransposón que incluye los genes de R. leguminosarum implicados en la síntesis de hidrogenasa, junto con un gen marcador de resistencia, que puede ser eliminado posteriormente. La introducción de esta construcción en bacterias de la familia Rhizobiaceae se ha realizado mediante transposición al genoma, donde se mantiene de forma estable. Las bacterias así modificadas inducen altos niveles de actividad hidrogenasa en los nódulos radiculares de leguminosas. Esta estrategia permite la obtención de cepas útiles como inoculantes rizobianos mejorados.

Abstract: A method and device for monitoring the operation of a component which is located in a sealed enclosure and is movable into a selected operating position in response to an activating signal uses the steps of: generating a short-duration acoustic signal in the enclosure in response to the movement of the component into the selected operating position; sensing the acoustic signal at the exterior of the sealed enclosure; and determining the time relationship between the activating signal and the acoustic signal. The acoustic signal is generated by an element which is carried by or moveable with the component and which generates the acoustic signal by striking an interior surface of the enclosure when the component moves into the selected operating position.
